THE NEW ROSS LINK TO AN IRISH LEGEND
Finn MacCumhaill was a distinguished chief who flourished in the 3rd century. He was son-in-law of King Cormac. He was commander of the Fianna, a body of several thousand warriors maintained by the Irish monarchs of that age. In peace they are said to have numbered 9,000, in war, 21,000. In winter they lived in small parties on the inhabitants of the country, while in summer they maintained themselves by hunting and fishing.
Ros Mhic Treoin in “Acallam na Senórach” is referred to as: That place was a hunting preserve to the Fianna and whenever in both Ireland and Scotland scarcity of game befell them, in ros mic Treoin they always had their sufficiency of hunting for three days and three nights.
